Motion Induced Blindness

Post  GEARHEADFLA on Thu Nov 08, 2012 10:09 am

In a motor accident, wherein a speeding car hits a slower moving vehicle
coming from the side, the speeding car drivers often swear that they just
didn't see the vehicle coming from the left or right.

Well, they aren't lying. They really don't see the vehicle coming from the
side, in spite... of broad daylight. This phenomenon on the car drivers'
part is known as "Motion Induced Blindness". It is unbelievable but it is
true, and it is definitely frightening. Armed forces pilots are taught about
motion induced blindness during training, because it happens faster at high
speeds; and to some extent it is applicable to car drivers also, especially
the fast ones. So, if you drive a car, please read this carefully.

Once airborne, pilots are taught to alternate their gaze between scanning
the horizon and scanning their instrument panel, and never to fix their gaze
for more than a couple of seconds on any single object. They are taught to
continually keep their heads on a swivel and their eyes always moving.
Because, if you fix your gaze on one object long enough while you yourself
are in motion, your peripheral vision goes blind. That's why it is called
motion induced blindness. For fighter pilots, this is the only way to
survive in air; not only during aerial combat, but from peacetime hazards
like mid-air collisions as well.

Till about three decades ago, this "heads on swivel & eyes moving" technique
was the only way to spot other aircraft in the skies around.

Now-a-days they have on-board radars, but the old technique still holds
good. Let me give you a small demonstration of motion induced blindness.
This is the same demonstration that is used for trainee pilots in classrooms
before they even go near an aircraft. Just click on the link below. You will
see a revolving array of blue crosses on a black background. There is a
flashing green dot in the center and three fixed yellow dots around it. If
you fix your gaze on the green dot for more than a few seconds, the yellow
dots will disappear at random..., either singly, or in pairs, or all three
together. In reality, the yellow dots are always there. Just watch the
yellow dots for some time to ensure that they don't go anywhere!

(You can alter the background color or the rpm of the array by clicking the
appropriate buttons.

So, if you are driving at a high speed on a highway and if you fix your gaze
on the road straight ahead, you will not see a car, a scooter, a buggy, a
bicycle, a buffalo or even a human being approaching from the side. Now
reverse the picture. If you are crossing a road on foot and you see a
speeding car approaching..., there's a 90% chance that the driver isn't
seeing you, because his/her peripheral vision may be blind! And you may be
in that blind zone!

Awesome Reality begetting once again, the ZEN of riding; we are invisible, no matter what.
The thing about pilots is what I love about a good sermon: DON'T tell me just WHAT to do, tell me HOW to DO it!
Got it. Range from gauges, to left mirror, right mirror, front, back to gauges, left mirror, right....
